Hydraulic Captive Reels

Redefining Load Management

Theresult of four years of intense development at Harken Italy’s dedicated facility, captive winches are offered with pulling loads of 1.5 to 50 tonnes and are available in both Electric and Hydraulic.

The Harken Captive Reel Winch has a large diameter hollow drum allowing high line lengths, combined with high load capacity, while reducing weight to the lightest on the market. The feeder screw ensures the line is loaded onto the drum in a neat, tight roll so that it pays in and out smoothly with complete control.

Designed for use with fiber ropes, it offers lighter and easier handling.

Self-lubricating lead screw and sheave allow line to lie smoothly on the drum, even when slack.

Precise gearing provides even line take-up and release.

Uses

Remotely control long lines.

Winch Features

The first 60 mm of the drum is knurled, increasing holding power of initial line wraps and reducing line needed for effective trimming. The feeder transmission features twin feeder screws to balance the load on the feeder sheave assembly. Double-screw design positions screws close to the drum, reducing winch size by 10%-20% over similarly configured winches. Automatic disc brake between motor and gearbox is locked unless system is activated.

Two inner magnetic switches factory set at the feeder’s stroke limits prevent overtravel. Two outer fail-safe limit switches automatically engage the brake. Using a synchronised transmission, four gears drive the twin feeder screws. Adjust line size by changing two gear sets on the motor end of the winch. The winch is driven by an industrial sealed hydraulic motor.

Materials

Winch frame and drum are 6061 Hardcoat anodized aluminum to reduce weight. Feeder screw nut and feeder skate are made of a self-lubricating composite. The gear cover is carbon fiber.

Maintenance

All parts connected to hydraulic or electric circuitry, screw bearings, and gear transmission are on motor side of winch for easy access. All bearings are sealed, and lubricated with grease. The main gearbox is sealed, and lubricated with oil.

Options

Line exits from the winch are available in left or right configurations. Two-speed or variable-speed hydraulic motors available. Captives come in 1.5T, 3T, 6T, 9T, 12T, 16T, 18t and 25T MWL
